Topic: Global warming, Greenhouse Effect and Climate Change.
Global warming can be defined as a phenomenon where the average temperature of the Earth increases. It happens when greenhouse gases such as carbon dioxide, water vapour, nitrous oxide and methane trap heat and light from the sun in the earth’s atmosphere. These gases emitted from cars and factories. These man-made gases absorbed the infra red heat from the sun and make the earth warmer than it should be as the gases trapped in the atmosphere. Human made chemicals called ‘chlorofluorocarbons’ that have been used in spray cans, refrigeration materials and air-conditioner caused the ozone depletion and contribute to global warming as well. It is one of the most serious challenges facing us today as this phenomenon brings about many dangerous consequences to natural environment on the earth as well as human being.
In our poster, we try to bring up some issues that contribute to global warming. The combustion of fossil fuels by automobiles, electric power plants and smelting and refining facilities releases waste gases such as carbon dioxide, sulfur dioxide and nitrogen oxide. The production of carbon dioxide from this activity is rising while the amount of plant life on the earth is shrinking. Therefore, we choose orange and yellow as the colour of earth as it is a sign our earth is sick and getting warmer from day to day. Then, some pictures that contribute to global warming such as cars, factories and open-burning on the earth. Then, we draw two hands below the earth in green and blue as it symbolizes our hands and we must work together to save the earth such as through the 3R principle, reduce, reuse and recycle.
Since the beginning of the Industrial Revolution, the amount of carbon dioxide produced by humans mostly from factories and automobiles has risen tenfold. Much of this carbon dioxide is absorbed by the oceans. To make matter worse, most...
